Raccoon Roundworms

Raccoon roundworms (Baylisascaris procyonis) are parasites that live in raccoon intestines. Raccoon roundworms lay many tiny eggs that are found in raccoon droppings. The eggs are not visible to the naked eye. If raccoon droppings are not properly cleaned up, the eggs mature in the droppings and can cause serious illness if accidentally swallowed. Even after raccoon droppings are cleaned up, eggs still may be present.
